Mayweather, unbeaten after 47 professional fights, and Pacquiao, an eight-division world champion, will now go head-to-head in a welterweight world championship unification bout at the MGM Grand Garden Arena in Las Vegas on May 2.
Pacquiao's trainer, Freddie Roach, and promoter, Bob Arum of Top Rank, are confident their man will come out on top.
Roach: "Floyd should enjoy being the A-Side while he can because on May 2 Manny is going to put him on his backside."
Arum: "It's going to a great fight. We are confident our fighter Manny Pacquiao will emerge victorious."
